Installation

Your spa may have come equipped with a 1/4” NPT threaded inlet on the air line, if not you may be required to drill and tap
a 1/4” NPT hole to install the 1/4” NPT to barbed adaptor that comes with the OE-001 kit. The location for the ozone
injection point will be decided by where you choose to place the adapter. Normally the placement of the adaptor will allow
the ozone to flow through only one side of the tub. If possible, choose the air line with the most attached jets to take full
advantage of the injection points. If drilling, place the adaptor downstream of the air vent controls. Your spa may have also
come supplied with a garden hose threaded tap on the HIGH PRESSURE SIDE of the pump, which is commonly referred
to as a power drain. If your spa has no power drain, then the optional saddle clamp must be installed on the HIGH
PRESSURE side of the pump as close to the pump as possible. If you are not sure which is the high pressure side, be sure
to contact your dealer to avoid any irreversible drilling. After you have located or installed the barbed adaptor on the air line
and the adaptor on the water line, simply hook up the eduction system as the diagram illustrates. Make sure all the
connections are sealed so no leaking will occur.
After all the water connections have been made you must choose a location for your ozonator. If you are locating the
ozonator below the water level an approved check valve (model #CHK-01B) must be used on the ozone induction air line
from the ozonator and the unit be hooked into an approved ground fault protected electrical supply. After the system is
totally installed, re-fill the tub. When tub level is correct, thoroughly inspect the system for leaks. If your spa was equipped
with a power drain, remember you must turn on the tap to allow water to pump through the system. If no leaks are found
turn the power on to the tub and open the jet that has the ozonated water connected to it and re-check for leaks. When the
unit is on high speed you should be able to detect suction at the inlet on the ozonator. If it can’t be detected, take the air line
off at the venturi to check the air draw into the venturi at high speed. At low speed the air draw will be dramatically reduced,
don’t be alarmed, there should only be a slight air draw at low speed. The retention loop has been incorporated to keep the
ozone in contact with the water prior to induction into the spa. This will cause excellent ozone absorption and mixing. If you
have a dominant ozone smell on high speed you simply need to increase the number of loops with an optional connector
until the ozone smell is almost eliminated. You should smell a slight hint of ozone at the jet that is introducing the ozone. If
you have no smell at all, simply cut the loop number back until you do smell a hint of ozone at high speed. ozone has a
distinct fresh or pungent odour.
